# Thinkable > Interactive STEM expeditions for children aged 10 and up. Every month a new mission in coding, data science and AI, worked through hands-on rather than watched. Self-paced, or in a live mentored crew for ages 10 to 14. Developed at KIT (Karlsruhe Institute of Technology) and tested with more than 400 children.
